Abstract X-ray diffraction on Ne implanted AISI 304 austenitic stainless steel revealedboth a tensile strain, which related to implantation itself, and a compressive strain in theunderlying substrate, which can be explained by the existence of Ne bubbles at high pressure.These two strains were measured and the principle and method for measuring it were ex-plained in detail. From the strain point of view, it was used to show the martensitic transfor-mation briefly.
